多功能汽液平衡测定仪的研究

Studies on Multipurpose VLE Determinating Apparatus

研制了1种多功能汽液平衡测定仪——CS-Ⅱ型VLE测定仪,阐述了该仪器的设计思想。该仪器兼有沸点仪和平衡釜的特点和功能,作为沸点仪,它具有泵结构搅拌器,可适用于拟静态法;作为平衡釜,它具有新型的汽液相取样结构和液相区冷却功能。可适用于完全互溶体系、部分互溶体系和高沸点差体系VLE的测定。本文给出了有关详细的实验考核结果。

This Paper presents a newly designed multipurpose VLE determinatingapparatus——CS- Ⅱ VLE determinating apparatus and discusses the ideas of theapparatus design. With the features and functions of both VLE still and ebulliome-ter, it has a pump-like stirrer so that it can be used appropriately to quasi-static method; it has a new structure of sampling vessels and valves, which makes it applicable to both miscible and partially miscible solution systems and appropriate to the system with high boiling temperature difference of components. The detail results of the experimental verification are given in this paper.
